Products advantages

1. Made from carburized alloy steel, work surface hardness to HRC58~62.

2. Taper accurary= AT3, ensure well contact with spindle cone for high speed

running to protect the spindle.

3. Concentrictity and runout =0.005mm in high rpm.

4. Surface"environment protection",special coating surface treatment,improve the

hardness and endurance of the surface,cleaness better,accuracy stable,surface
more smooth,antirust,feel comfortable,apperance nice.
